[Kernbigo]

Does lee make a mold 45 cal. around 250gr., needs to be oversize to resize to.451 for 50 cal muzzleloader with sabots thanks kernbigo

Yes, the 90356 is a reproduction sorta of the 454424 Keith SWC and their 90358 is their take on the old 454190 with a bigger Meplat. Both are in the 250-255gr range.

Here's a link to their page so you can view them:

I checked out the wbe site and I gather you don't have to resize they come out .452 and run with in .001 out of round if that is true.Did you find that to be fact? Kernbigo

Do you feel lucky? Better figure on buying a sizer.

I have the 90287 TL452-130 TC (casts at .452-.453 and 242 grains using wheel weights) and the 90358 452-255 RF (casts at .452 and 247 grains using the same alloy).

Hope this info helps you.

If I buy the lee 90358 mold And there is no stock to resize, how important in a 50 cal. H&R inline 1-28 twist using a sabot is concentricity? Kernbigo

I am not certain the concentricity is going to make any measurable difference.

Concentricity will not guarantee that the center of mass will be at the center of the projectile.

I just now measured one and found the maximum difference in diameter to be less than .0012 - that is 1.2 thousandths of an inch. This boolit came from one of my reject piles and was fugly.

I suspect less discrepancy in any that I save.
